• Convertible to thermostatic control, also when installed
and in operation
• Robust valve housing made of corrosion resistant red
bronze with good flow and sound properties
• Maintenance-free spindle sealing
• Valve housing with dimensions according to EN215,
Appendix A, Series D
• Non-rising handwheel
• Connection to all types of pipe DN10...DN20
Straight

copper or precision steel pipe on inlet (compression ring
fittings see ‘Accessories’)
• external thread connection to DIN/ISO228 with union-nut
and radiator tailpiece on outlet
• Valve insert

Function
The orifice between valve seat and valve cartridge increases
when the valve is opened by turning the handwheel anti-clockwise. More heating water can flow into the radiator or heat
exchanger and the room temperature rises.
The orifice between valve seat and valve cartridge decreases
when the valve is closed by turning the handwheel clockwise
and the supply of heating water into the radiator or heat
exchanger is throttled. At the right limit stop the valve is closed
except for a possible leakage rate.
Dimensions and Ordering Information
Please Note:
• To avoid stone deposit and corrosion the composition of the
medium should conform with VDI-Guideline 2035
• Additives have to be suitable for EPDM sealings
• System has to be flushed thoroughly before initial operation
with all valves fully open
• Any complaints or costs resulting from non-compliance with
above rules will not be accepted by Honeywell
• Please contact us if you should have any special requirements or needs
